No. Internet email standards require that for reliable transmission the content of messages must consist of only 7-bit ascii characters. Thus, headers, message body parts, etc. containing non-ascii characters must be encoded for transmission. The encoding is either quoted-printable or base64. What you are seeing is a quoted-printable encoding of the UTF-8 encoding of these characters. This is either in a body part whose Content-Transfer-Encoding: is quoted-printable or an RFC2047 quoted-printable encoded word in a header. > The received email from the mailing list do not have this kind of issue > though. Because the MUA viewing the mail knows how to decode it for display. If you look at the raw message text, it will be the same. The list's archives/private/listname.mbox/listname.mbox file contains the raw messages as sent. Why do you care? If you are using tools like grep to search the cumulative mbox or the periodic .txt files in the archive, there are more serious issues because many things will be base64 encoded which is not human readable at all.
